CAN-COVER REMOVER.

Specification of Letters Patent.

Patented Nov. 2, 1920.

Application filed February 7, 1920. Serial No. 356,876.

To all fui/om 'it may concern:

Be it known that I, HARRY B. SIEGMUND, a citizen of the United States,residing at Baltimore city, State of Maryland, have invented certain newand useful Improvements in Can-Cover Removers, of which the following isa specification.

This invention relates to devices for facilitating the removal of thelids or covers of milk cans or other receptacles having a tight-fittingclosure which is usually diihcult to remove, and the object of theinvention is to provide a very simple and eiiicient device of this kindwhich is powerful in action so that the removal of an abnormally tight`fitting lid may be readily eiected.

The object stated is attained by means of a novel combination andarrangement of parts to be hereinafter described and claimed, and inorder that the same may be better understood, reference is had to theaccompanying drawing forming a part of this specification.

In the drawing- Figure 1 is an elevation of the device; Fig. 2 is avertical section of the device showing the manner in which it is used,and Fig. 3 is a plan view thereof. c

Referring specifically to the drawing, 5 denotes a fragment of a milkcan or other container, provided with a tight-tting 11d 6. The devicefor effecting the removal of the lid comprises a supporting member and alever mechanism for exerting an upward thrust or pull on the lid.

The supporting member is a cylinder 7 open at both ends, and reinforcedby top and bottom rings 8 and 9, respectively. The" inside diameter ofthe cylinder is such that it may be slipped down over the neck of thecan 5 to inclose the lid 6, as shown in F ig. 2, the bottom ring 9seating on the top of the can, and the latter therefore serving as asupport for the cylinder.

On the top ring 8 are outstanding ears 10 to which are pivoted, as shownat 11, hand levers 12, two diametrically opposite ones of such leversbeing provided. The pivoted ends of the levers have lateral bends 13,and the levers are therefore of the bell-crank type. The bends 13 passthrough vertical slots 14 in the cylinder 7, and inside the latter, theycarry depending lifting links 15, said links being pivoted to the leverbends, as shown at 16. The links 15 have on their edges which face thelid 6, a vertical series of hooks 17, any one of which is engageablewith the edge of the lid, as shown in Fig. 2.

By providing the links with a plurality of hooks, the device is readilyapplicable to cans of different dimensions.

Adjacent to the points of attachment of the links l5 to the lever bends13, the latter have outstanding abutments 18, which may be pins. Theseabutments are opposite the edges of the links which have the hooks 17.

In use, the cylinder 7 is seated on top of the can 5 as shown in Fig.2.. Before this can be done, it is necessary to swing the lifting linksoutwardly a sufiicient distance to clear the lid G. This is donc bygathering or bringing the hand levers 12 together. IVhen this is done,the abutments 18 are carried against the links, and the latter are swungoutwardly, as shown in Fig. 1. The links are free to swing in thismanner as they are pivoted to the flevers. After the cylinder has beenproperly positioned on the can, the levers ai'e spread slightly to allowthe links to swing inwardly for the engagement of their hooked edgeswith the lid, as shown in Fig. 2. The levers are now grasped and spread,whereupon the links are drawn upwardly, and the lid is forced olf thecan. A powerful leverage is obtained, and hence a tight-fitting lid isvery readily removed.

I claim:

1. A device of the character described, comprising a cylindricalsupporting member open at its ends, pivoted levers laterally bent attheir pivoted ends, carried by said member, lifting links pivoted tosaid levers on said bent portions, thereby causing said lifting links tobe drawn upwardly upon the spreading of said levers.

2. A device of the character described, comprising a cylindricalsupporting member open at its ends and having side slots, pivoted leverscarried by said member, lifting links carried by the levers andpositioned inside the supporting member opposite the side slots, andmeans on the levers for swinging the links outwardly through said slots.

3. A device of the character described, comprising a cylindricalsupporting member open at its ends and having side slots, pivoted leverscarried by said member, lifting links pivoted to the levers andpositioned inside the supporting member opposite the side slots, andabut-ments on the levers intercepting the links for swinging the sameoutwardly through the slots.

In testimony whereof I aiiix my signature.

HARRY B. SIEGMUND.
